The condition wherein the pressure inside the eye builds up
to dangerous levels due to lack of proper drainage of the
aqueous humor, the clear, salt water substance that fills
the cavity that lies between the cornea and the inner lens
of the eye. If left untreated, the condition can cause
damage to the optic nerve, with a resulting loss of vision.
Since the most common form of glaucoma has few recognizable
symptoms, a regular eye examination is very important for
anyone over 40 years of age and particularly for those who
have a history of glaucoma in the family. Persons with
severe cases of glaucoma are usually not good candidates for
refractive eye surgery.
